BAAR, SWITZERLAND--(Marketwire - December 4, 2009) - Manas Petroleum Corporation (OTCBB: MNAP) is pleased to report that DWM Petroleum, its 100% owned subsidiary, has completed its year-1 work program on blocks 13 and 14 in Mongolia, ahead of schedule. The work was originally expected to be completed on April 21, 2010.
